inetpeer: Abstract address representation further.
Future changes will add caching information, and some of these new elements will be addresses. Since the family is implicit via the ->daddr.family member, replicating the family in ever address we store is entirely redundant. Signed-off-by: David S. Miller <davem@davemloft.net>
